From 15eeb6d96096659aae0f8a5e7c4fbdb704886fa9 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Sat, 21 Aug 2021 13:08:09 -0700 Subject: weston: Re-order gbm destruction at DRM-backend tear down Fixes an annoying segfault seen on rpi4 when launching weston during boot especially using systemd service or sysvinit script, if weston is launched manually on VT, it works fine.
